⚡ The Challenge: A Dormant Database Worth ₹50 Lakhs
NutriPlus Health Foods, a Delhi-based D2C brand selling premium plant-based protein and organic snacks, had built a respectable email list of 45,000 subscribers over 3 years. But in early 2023, their email channel was bleeding potential revenue:
- 8% open rate – far below the industry average of 21-25% for health/food brands
- 0.4% click-through rate – meaning 99.6% of subscribers ignored every email
- Revenue contribution: Less than 5% of monthly sales, despite 45K subscribers
- Klaviyo setup: Was installed but never configured properly – no welcome flows, no abandoned cart sequences, no segmentation
- List hygiene: 12,000+ inactive subscribers (26.7% of list) had not opened an email in 6+ months
The founder, Rohan Mehta, told us: “We knew our customers loved our products – repeat purchase rate was 38%. But our emails looked like spam. We were leaving lakhs on the table every month.”
With an average order value of ₹1,850 and 45,000 subscribers, AK Network Solutions calculated the unrealized monthly revenue potential was ₹83 lakhs – if the channel could be optimized to industry benchmarks.
🎯 Our Strategy: The 5-Pillar Klaviyo Rebuild
AK Network Solutions deployed a data-first, automation-heavy approach using Klaviyo as the core engine, integrated with WhatsApp for SMS fallback. Our strategy hinged on 5 pillars:
Pillar 1: List Hygiene & Segmentation (Week 1-2)
- Re-engagement campaign: 3-email sequence to 12,000 dormant subscribers with “We miss you” offers
- Hard bounce removal: 2,300 invalid addresses cleaned from the list
- Segmentation by behavior: Created 9 segments – VIP (spent ₹10K+), repeat buyers, single-purchase, cart abandoners, new subscribers, etc.
- Purchase history tagging: Tagged every subscriber by product category (protein, snacks, supplements) and purchase frequency
Pillar 2: Flow Architecture (Week 3-5)
We built 7 automated flows from scratch:
- Welcome Series: 4-email sequence over 7 days – first email within 5 minutes of signup, including a 15% discount code
- Abandoned Cart: 3-step sequence (1 hour, 12 hours, 24 hours) with product recommendations and urgency triggers
- Post-Purchase: 5-email sequence – order confirmation, shipping update, product usage tips, review request, cross-sell
- Win-Back: 3 emails over 14 days for customers inactive 60+ days
- VIP Flow: Exclusive early access and birthday offers for top 5% spenders
- Browse Abandonment: Triggered when users viewed product pages 3+ times without purchase
- Replenishment Reminder: Timed at 30 days post-purchase for consumables (protein powders, snacks)
Pillar 3: Design & Copywriting Overhaul (Week 4-6)
- Mobile-first redesign: 72% of opens were on mobile – all templates rebuilt for thumb-friendly CTAs
- Personalization at scale: Dynamic content blocks showing product recommendations based on past purchases
- Subject line A/B testing: Tested 3 variants per campaign – emoji vs. no emoji, personalization vs. generic, urgency vs. curiosity
- Preheader text optimization: Added actionable hooks like “Your protein is running low, Rohan”
Pillar 4: SMS Integration (Week 5-6)
Integrated Klaviyo with WhatsApp Business API via Twilio for fallback SMS on high-value flows (abandoned cart, win-back). This added a 12-15% lift in conversion rates for these flows.
Pillar 5: A/B Testing Programme (Ongoing from Week 4)
We ran continuous A/B tests on:
- Send time optimization (morning 7 AM vs. evening 8 PM – evening won by 23%)
- Discount depth (10% vs. 15% vs. 20% – 15% had highest ROI)
- Email length (short 50-word vs. long 200-word – short won for mobile)
- CTA button colors (orange vs. green – orange increased CTR by 18%)

💡 Key Takeaways: What Made This Work
- Segmentation is non-negotiable. Generic blasts to 45K subscribers fail. Our 9 segments allowed us to send the right message to the right person at the right time – the abandoned cart flow alone generated 18.4% recovery.
- Welcome series is your highest-leverage asset. New subscribers who received our optimized 4-email sequence had a 12.3% purchase rate in 7 days, compared to 1.8% before. First impressions matter.
- List hygiene directly impacts deliverability. Removing 7,100 inactive subscribers improved our sender reputation, lifting open rates from 8% to 34%. A smaller, engaged list outperforms a large, stale one.
- A/B testing is a multiplier. Continuous testing of subject lines, send times, and CTAs gave us compounding gains. The winning subject line variant (personalized + emoji) had 2.3x higher open rate than the control.
- Integration amplifies results. Adding WhatsApp fallback for high-value flows (abandoned cart, win-back) added 12-15% lift. The combination of email + SMS creates a powerful 1-2 punch.
- Data-driven personalization works. Using purchase history to recommend complementary products (e.g., protein powder with shaker bottle) increased average order value by 21%.
